A novel approach to directly achieve SiO2 hollow nanofibers via mono-axis electrospinning united with fluorination technique
Materials Letters（2023）
Abstract
•A technique of mono-axial electrospinning united with fluorination is established.•Facile and low-cost fabrication of silica hollow nanofibers is successfully realized.•Only fluorination can form silica hollow nanofibers among the halogenation processes.•Diameter and wall thickness are tunable by varying tetraethyl orthosilicate amounts.•Possible formation mechanism of silica hollow nanofibers is proposed and verified.
